Mainline Propeller Meters
Models 111/112 — Plain End Tube Type
Description
150 psi (10 bar) Working Pressure, 300 psi (20 bar) Working Pressure, Magnetic Drive Sealed Gear Housing,
Sizes 4” through 36” (DN 100mm—DN 900mm)
Sensus Propeller Meters are intended for
accountability measurement of potable or
non-potable cold (to 100°F/38°C) water
where flow is in only one direction. The
meters can be installed at any convenient
angle from horizontal to vertical; in
discharge, suction or pressurized lines;
within stated pressure ratings. For accurate
measurement, a full flow of water through
the meter and stated minimum flow rates
are required. Because all appropriate parts
are sealed for protection, the meters can be
used with water containing particulate solids
(as sand), without causing undue wear.

Features
CONSTRUCTION
REGISTERS
The meters are produced of fabricated
steel and protected internally by an epoxy
paint.
Sensus Propeller Meters are available with
a standard sealed mechanical register
(Model 111) or a sealed Electronic Rate
of Flow Instrument and Transmitter—EROFI (Model 112).
MAGNETIC DRIVE
Eliminates mechanical packings and
stuffing boxes. A sleeve-type ceramic
magnet in the propeller assembly drives a
follower magnet located within the sealed
gear box.
RIGHT ANGLE GEARING
The brass bevel gears, which drive the
register shaft, operate within a factorysealed, oil-filled, one-piece cast bronze
gear box, providing lubrication for the life
of the meter.
CERAMIC BEARING AND SHAFT
The double land ceramic bearing retained
in the propeller assembly rotates on a
ceramic sleeved shaft. The high purity
ceramic provides exceptionally good wear
characteristics, even in water containing
entrained solids.
INSTRUMENTATION CAPABILITIES
The E-ROFI or High-Speed Pickup Registers are available for interfacing with Sensus Act-Pak Instruments. Refer to Bulletin
E-1116 for HSPU and Bulletin E-1110 for
E-ROFI Register.
INSTALLATION
The meter is installed in the pipeline
similar to placing a short length of plain
end pipe in the line either by welding,
brazing or using pipe couplings, such as
Smith-Blair #411 flexible couplings. The
meter must have a full flow of liquid to
assure proper registration. Valves, fittings
and other equipment which may create a
flow disturbance, should be positioned at
least five pipe diameters upstream, and
three to five diameters downstream from
the meter.
GASKETS
A flat gasket is used at the connection
of the meter head to the body on 4” (DN
100mm) through 8” (DN 200mm). An
“O” ring is used on 10” (DN 250mm) and
larger sizes.
MAINTENANCE
Should maintenance or testing be eeded,
the meter head can be removed without
disturbing the tube body in the pipeline.
Cover plates are available for maintaining
service or flushing of lines when the meter
head is removed.
